Question 1

What is keyword density and why does it matter?

Accepted Answer

Keyword density is the percentage of times a keyword appears relative to the total word count. While Google has moved beyond simple keyword density as a ranking factor, it's still a useful diagnostic tool. Extremely low density may mean you're not targeting the topic clearly enough, while very high density may appear as keyword stuffing.

Question 2

What is the ideal keyword density for SEO?

Accepted Answer

There is no single ideal density. Most SEO professionals suggest a range of 1-3% for primary keywords, but this is a guideline, not a rule. Modern search engines use semantic analysis and topic modelling rather than exact keyword matching. Focus on writing naturally about your topic rather than hitting a specific percentage.

Question 3

What are stop words and should I exclude them?

Accepted Answer

Stop words are common words like 'the', 'a', 'is', 'and', 'to' that appear frequently in all text. Excluding them reveals the meaningful keywords in your content. This tool lets you toggle stop word filtering on or off so you can see both views.

Question 4

What are bigrams and trigrams?

Accepted Answer

Bigrams are two-word phrases and trigrams are three-word phrases. Analysing these multi-word patterns reveals important keyword phrases in your content. For example, 'content marketing' (bigram) or 'search engine optimisation' (trigram). These are often more useful than single-word analysis for understanding topic coverage.

Question 5

How is keyword density different from TF-IDF?

Accepted Answer

Keyword density measures how often a word appears in a single document. TF-IDF (Term Frequency - Inverse Document Frequency) goes further by comparing word frequency against a corpus of documents, revealing which words are uniquely important to your content versus commonly used across all documents. TF-IDF is more useful for competitive content analysis.
